Exploitation Of Relay Coordination Software On Power System Equipments Protection

The collocation of the protective relay for main equipments of power system is very complicated, which exists with the bigger difference in various power plant or transformer substation. The principle and pattern of protection are renewing continuously, the protection device comes from the different factory, their setting calculation is different. The thesis develops the practical relay coordination software for main equipments of power system. This software according to the basic principle of setting calculation, combines the characteristics of each protection device, takes database as its core, applies Object Oriented Programming and modularization technologies,carry out the purpose that use computer to do protection setting calculation, which has good generality and practicality.
